February 23, 2018 #TriCitiesWx Forecast

As of almost 4 PM, we’re close to yet another record high! The record is 79 degrees, and we’re at 78 late this afternoon. Record heat comes to an end and rain moves in during today’s Tri-Cities Weather Blog forecast.

There were a few rain showers as close to us as southeast Kentucky, but we’ve been dry for the most part outside today. Rain chances go up late tomorrow afternoon, though, and continue through much of the weekend. Here’s the outlook:

Tonight-Partly cloudy. Low 54.

Saturday-Increasing clouds, with afternoon showers and storms developing. High 74.

Saturday night-Cloudy with a few rain showers. Low 55.

Sunday-Mostly cloudy with scattered showers and storms. High 68.

Monday-Partly to mostly cloudy with a few rain showers. High 63.

Tuesday-Partly to mostly sunny. High 65.

We’ve had high pressure blocking a cold front that’s tried to get here for a couple days now. A warm front has gone through, which is the reason for all of our recent warm weather and record temperatures.

Eventually, a strong enough cold front will break through the blocking system and move into our area. That should happen late Saturday, and it will increase our chances of showers and possible thunderstorms as early as Saturday afternoon.

We’ll get a break Saturday night for a brief time before the front itself arrives on Sunday. We should have quite a lot of rain and possible thunderstorms on Sunday, and some of that might continue into early Monday as well. By the end of Monday, dry weather should be back, with a mainly sunny day coming up on Tuesday.
